To me, “wealthier personal life” is a little ambiguous. If you mean someone has a lot of money, you say they are wealthy, not that they have a wealthy personal life. A rich personal life would mean that the person has a fulfilling, interesting life. So I would probably take wealthy personal life to mean the same thing, but I still wouldn’t feel 100% sure your weren’t just talking about money.

For me, “wealthier personal life” is that by receiving a good education you will be able to achieve some milestones in your life as well as a good salary. So I think that “wealthier personal life” is referring to the amount of money you have. However, I can suggest using some grammar checkers like Robotdon to be sure that this sentence is correct.
